UPDATE 1-Brazil's Embraer books steady commercial deliveries, backlog

SAO PAULO, July 11 (Reuters) - Brazilian planemaker Embraer
SA kept its commercial jet deliveries and order
backlog roughly steady in the second quarter and wound down
sales of an unprofitable executive jet that weighed on earnings
in recent years.

The world's third-largest producer of commercial jets
delivered 26 E-Jets to airlines from April to June, one fewer
than a year earlier, according to a securities filing on Monday.

Executive jet deliveries fell to 26 aircraft from 33 in the
second quarter of 2015. Embraer delivered none of its large
Legacy 650 business jets, which are built on an old regional jet
platform and have struggled to compete against newer rivals amid
a glut of executive aircraft in a weak market.

Last month, Embraer announced the end of Legacy 650
production in China, ending a 13-year joint venture.

The company's backlog of firm orders, a gauge of future
revenue, held steady in June at $21.9 billion, in line with its
March backlog due to a 30-jet order from the Horizon Air
affiliate of Alaska Air Group Inc.

Separately on Monday, Embraer announced that it had reached
an agreement with Boeing Co to support the Brazilians'
KC-390 military cargo aircraft, building on a 2012 joint sales
deal in select markets.

The KC-390, which took its first flight in early 2015 and is
now on a tour of eight countries, is on schedule for
certification by the end of next year and deliveries beginning
in the first half of 2018.
